working on covering the wings right now, I've used Sig Koverall an Sig Stixit, then painted several layers of Poly/babypowder mix to fill in the cloth, then sand smooth an primered, so far I've built a working skid, got the fuse covered, sheeted the bottom of the LG Wing, made a battery door on the belly using hinges an magnets to hold it closed.
Trying to figure out how to rig up lower wing skids, may just scratch it an add some carbon fiber skids to protect it, won't weigh as much an won't notice them either, still working on that one.

Original skids on the wingtips of full scale prototype were actually axe handles, to keep from breaking the wingtips because the aircraft is so top-heavy and the gear is so narrow.
The production skids always looked a lot like axe handles.

Since you probably WILL drag the skids, make them from wood and cut small slots to insert music wire so when it skids, it rubs the wire, not the wood. Done well you can hide the wire with just a bit of the correct color brown paint.
